Alabama was last an underdog to LSU in 2007, Nick Saban's first season. During that span, though, the Crimson Tide is just 3-2 against the Tigers.

During the preseason, LSU was listed as a 2-point favorite over Alabama.

As it currently stands, it's the most Alabama has been favored to win by against LSU since 1999, when it entered the annual matchup as a 20-point favorite. It won that game, 23-17.

This marks the first time Alabama has been favored by fewer than double digits since the BCS national title game, when it easily covered the 2.5-point spread with a 21-0 blanking of the Tigers.

Alabama hasn't been an underdog since the 2009 SEC Championship Game against Florida. The Crimson Tide more than covered that spread, routing the Gators, 32-13, after it was listed as a 4.5-point underdog.

LSU hasn't been this big of an underdog at home since its 2009 game against Florida. The Tigers failed to cover the 9.5-point line, falling 13-3. That just so happened to be the last time LSU lost at home, as it currently rides a program-record 22-game home winning streak into Saturday's primetime game.

The Crimson Tide has covered the spread in five of its eight wins this season, four of which coming against SEC foes.
